Restart After Going to Sleep Mode

My computer is set to go to sleep after 15 minutes of inactivity. Within the last week, every time my computer goes to sleep, I receive a BSOD and my computer restarts. It wakes up fine and prompts me for my password (I require a password on start up).

How do I fix this BSOD?

I have attached my minidump files.

BTW, I am using Windows 7 64-bit
